Answer:

The correct answer will be option- permits complementary base pairing

Explanation:

DNA contains four types of nitrogenous bases which pair with one another,  identified by Erwin Chargaff.  

Chargaff suggested that adenine binds thymine forming two hydrogen bonds and cytosine binds guanine forming three hydrogen bonds.

This base pairing between the complementary groups is known as a complementary base pairing which plays an important role in DNA.

The complementary base pairing allows the formation of the helical structure of DNA, the base pairs to be arranged in most energetically and favourable way and replication and transcription processes.

Thus, permits complementary base pairing is the correct answer.

nirvana33 [79]

Answer:

50%

Explanation:

DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.

However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).
